防震减灾、应急准备和反应及恢复重建的社会学问题

尽管灾害几乎在地球上开始出现以来一直给人类带来灾祸(《创世纪》6—8和《基督》8—10将此种灾害看作是上帝的行动)，尽管许多灾害(如：1666年伦敦大火、1755年里斯本地震、1871年芝加哥大火、1906年旧金山地震，这里仅列4例)已载入编年史，但是在1920年S．H．Prince向哥伦比亚大学提交有关军火船爆炸造成2000多人死亡的1917年哈利法克斯灾难的学位     

THE SIGNIFICANCE OF THE SINAL FORMULA IN DEVONIAN AND POST-DEVONIAN SPIRIFERS

Recent study, has brought out the fact that members of the Spiriferidae, in which the sinus is plicated, are divisible into a series of distinct gronps, each of which shows a definite order of appearance of the plications in the sinus of the pedicle valve.     

MEMORIAL OF YATSENG T. CHAO

The death of Mr Y T. Chao at the hands of bandits in Yunnan is a tragedy, the magnitude of which few can realize, and a loss to China which is absolutely irreparable. Modern science in China is so young and able men of science are so few, that the ruthless cutting off, at the very threshold of his     

TERMS FOR THE SHELL-ELEMENTS IN THE HOLOCHOANITES.

In 1918, at the meeting of the Palaeontological Society of America, I first advanced the proposition that the shell of the Holochoanites (Proterocameroceras, Cameroceras, Endoceras, Vaginoceras etc) was not the homologue of the shell of the Orthochoanites (Orthoceras etc) but that it was only the so-     

REVISED CLASSIFICATION OF THE PALEOZOIC SYSTEMS IN THE LIGHT OF THE PULSATION THEORY

The Chronological classification of the rocks of the Earth's crust beganin the 18th century when John Strachey in England,Giovanni Arduino inItaly and Lehman,Füchsel,and Werner in Germany began their subdivisionon the lithological and structural basis.     

V.K.Ting,Scientist and Patriot.

In the lamented death of Dr. V. K. Ting on January 5th, 1936, at the age of49, China suffered an irredeemable loss. He may be called the founder of thescience of geology in China, and it was in geological field work that his con-     

南极洲赖特谷万达盐湖中铬的垂直迁移

南极洲万达湖湖水上部为氧化环境,铬浓度较低,Cr~(6+)占主导地位,主要以CrO_4~(2-)形式存在;下部为还原环境,铬浓度高,Cr~(3+)为主,以Cr(OH)_2~+和Cr(OH)~(2+)形式存在。湖水中锰、铁的氧化物及氢氧化物颗粒对铬离子的吸附和释放过程,控制了湖水铬浓度的变化。     

THE EFFECT OF MINE TAILINGS ON LEVELS OF HEAVY METALS IN SEAWATER

Changes in levels of heavy metals in seawater resulting from the addition of mine tailings were studied using plastic enclosures. Nominal concentrations of 10 mg l-1 and 100 mg l-1 of mine tailings from a B. C. molybdenum mine were added, and the metal levels were followed together with sedimentation rates, particle size distribution and other oceanographic and biological time-series parameters over sixteen days. No substantial elevation in levels of zinc, cadmium and copper was observed in the tailing bags compared to that in a background control bag with no addition of tailings. Lead showed a substantial increase in seawater following tailing addition and its removal apparently was with detritus settling following a plankton bloom, and inorganic settling of fine tailing particles.     

Environmental monitoring of the Zhujiang Estuary and its coastal waters

The Zhujiang (Pearl River) Estuary is a complex water system whose catchments basincovers a very large part of southern China. The large quantity of fresh water carried by the river system flows into the northern coast of the South China Sea through its eight inlets. The Zhujiang River Delta has experienced the fastest economic growth in China during the past two decades. Rapid population expansion and increased industrial development coupled with insufficient waste management turned the Zhujiang Estuary into waste disposal channels just before entering the coastal waters. The water quality of the estuaries and the coastal oceans has become polluted. During the past two years, an intensive study and monitoring efforts of the pollutions of these waters have been made. A systematic and integrated monitoring task including shore-based measurements, shipboard in-situ measurements, and satellite and radar remote sensing surveys has been completed.
